Please refer to the prior art for details and will not be repeated here.

[0039] The nebulizer 1 includes a housing 11, an atomizing core 12, a spray assembly 13, and a liquid storage bottle 14. The liquid storage bottle 14 serves as a liquid storage chamber for storing an aerosol-generating matrix. The spray assembly 13 is connected to the liquid storage bottle 14. The spray assembly 13 is used to spray the aerosol-generating matrix onto the atomizing core 12 so that the atomizing core 12 heats the aerosol-generating matrix to generate an aerosol. The housing 11 has an installation space 111, and the atomizing core 12 and the spray assembly 13 are accommodated in the installation space 111. The liquid storage bottle 14 can be accommodated in the installation space 111 or can be arranged outside the installation space 111. The specific arrangement is based on actual conditions. The spray assembly 13 is used to spray a predetermined flow rate of aerosol-generating matrix onto the atomizing core 12 to generate droplets, and the atomizing core 12 is used to atomize the droplets to generate an aerosol. The size of the droplets in the aerosol is much smaller than the size of the droplets sprayed by the spray assembly 13. The predetermined flow rate refers to the constant mass of the matrix to be atomized sprayed per unit area by the spray assembly 13 per unit time. For example, the predetermined flow rate is 3mg / s / cm 2 , 5mg / s / cm 2 wait.

[0040] In this embodiment, the spray assembly 13 includes a micropump 131 and a nozzle 132. The micropump 131 is used to transfer the aerosol-generating substrate in the liquid storage bottle 14 to the nozzle 132 through negative pressure, so that the aerosol-generating substrate is sprayed to the atomizer core 12 through the nozzle 132. Specifically, the nozzle 132 may include a main channel 1321, a tapered channel 1322, and a spray portion 1323. The liquid storage bottle 14 may include a liquid storage chamber 141 and a liquid supply section 142. The liquid supply section 142 connects the liquid storage chamber 141 and the nozzle 132 to transfer the aerosol-generating substrate in the liquid storage chamber 141 to the nozzle 132.

[0041] The micropump 131 can be controlled by the battery 21 or manually to transfer the aerosol-generating substrate from the liquid storage bottle 14 to the nozzle 132. The micropump 131 controlled by the battery 21 can be a piston pump or a vacuum pump. In other embodiments, the micropump 131 can also use other methods to transfer the aerosol-generating substrate from the liquid storage bottle 14 to the nozzle 132. During atomization, the micropump 131 is used to provide a predetermined flow rate of aerosol-generating substrate to the atomizer core 12.

[0042] In another embodiment, the spray assembly 13 includes a nozzle 132. The liquid reservoir 14 is a high-pressure liquid reservoir. The aerosol-generating substrate in the reservoir is under high pressure. The nozzle 132 is connected to the high-pressure liquid reservoir via a pipe, and a switch is provided on the pipe. By controlling the switch, the aerosol-generating substrate in the high-pressure liquid reservoir can be sprayed through the nozzle 132 toward the atomizing core 12 to form droplets. The atomizing core 12 heats the droplets to generate an aerosol.

[0043] In this embodiment, the atomizing core 12 includes a heating element, which is used to heat and atomize the droplets sprayed by the spraying assembly 13 to generate aerosol. The heating element can be a heating plate or a heating net.

[0044] In one embodiment, when the heating element is a heating plate, and the directions in which the heating plate and the spraying assembly 13 spray the aerosol-generating matrix are perpendicular to each other, a gap is left between at least one side of the heating plate and the inner wall surface of the installation space 111. The aerosol generated by the heating plate heating and atomizing the aerosol-generating matrix is ​​transmitted to the air outlet channel 17 through the gap between the heating plate and the inner wall surface of the installation space 111 for the user to inhale.

[0045] In one embodiment, when the heating element is a heating net, and the heating plate and the direction in which the aerosol-generating substrate is ejected from the ejection assembly 13 are perpendicular to each other, at least one side of the heating net is fixedly connected to the inner wall of the installation space 111. In this embodiment, the periphery of the heating net is fixedly connected to the inner wall of the installation space 111. The aerosol generated by the heating net heating the aerosol-generating substrate ejected from the ejection assembly 13 can be directly transmitted through the heating net to the air outlet channel 17 for inhalation by the user.

[0046] In one embodiment, the heating element is a heating plate, and the heating plate is parallel to the direction in which the aerosol-generating substrate is ejected from the ejection assembly 13. In other words, the heating plate is positioned to the side of the region in which the aerosol-generating substrate is ejected from the ejection assembly 13, and the heating plate heats and atomizes droplets of the aerosol-generating substrate to generate an aerosol.

[0047] In this embodiment, the angle θ between the heating net or heating plate and the direction of spraying the aerosol generating substrate may be in the range of 0≤θ≤90. The specific setting method and setting angle may be set according to actual conditions.

[0048] In one embodiment, the nebulizer 1 further includes a temperature sensor 15 , which is disposed on the inner wall or outer wall of the liquid storage bottle 14 , and is used to monitor the temperature information of the aerosol generating matrix in the liquid storage bottle 14 in real time.

[0049] In another embodiment, the nebulizer 1 includes a viscosity sensor 16, which is disposed on the liquid storage bottle 14 and is used to monitor the viscosity of the aerosol-forming substrate in the liquid storage bottle 14 in real time. The viscosity sensor 16 can be disposed on the inner wall of the liquid storage bottle 14, such as the bottom wall or the side wall, so that the viscosity of the aerosol-forming substrate can be detected even when the aerosol-forming substrate in the liquid storage bottle 14 is low. The viscosity sensor 16 can also be disposed on both the inner wall and the side wall of the liquid storage bottle 14 so that when the aerosol-forming substrate in the liquid storage bottle 14 is low, the viscosity of the aerosol-forming substrate can be detected regardless of whether the nebulizer 1 is in a horizontal or vertical orientation.

[0050] The battery rod 2 is coupled to the atomizer 1 and is used to power the heating element in the atomizer 1 and control the heating element to heat the atomized aerosol to generate the substrate. The battery rod 2 is also used to power the micro pump 131 to control the operation of the micro pump 131.

[0051] In one embodiment, the battery rod 2 includes a battery 21, a processing unit 22 and a storage unit 23. The processing unit 22 is electrically connected to the battery 21 and the storage unit 23, respectively. The battery 21 is used to power the atomizer 1 and the micro pump 131. The storage unit 23 is used to store the temperature-working voltage relationship and the viscosity-working voltage relationship. The processing unit 22 is used to receive the temperature information or viscosity information of the aerosol generating matrix monitored in real time by the temperature sensor 15 or the viscosity sensor 16, and to bring the received temperature information into the temperature-working voltage relationship to analyze and obtain the working voltage of the micro pump 131, or to bring the received viscosity information into the viscosity-working voltage relationship to analyze and obtain the working voltage of the micro pump 131, so that the injection assembly 13 can inject a predetermined flow of aerosol generating matrix into the atomization core 12.

[0052] In one specific embodiment, the processing unit 22 is configured to obtain temperature information of the aerosol-forming substrate detected by the temperature sensor 15, apply the received temperature information to the temperature-operating voltage equation, analyze the temperature information to determine the operating voltage of the micropump 131 corresponding to the current temperature information, and control the voltage output by the battery 21 to the micropump 131 to be the operating voltage corresponding to the current temperature information, thereby adjusting the rotation speed of the micropump 131 and causing the injection assembly 13 to inject a predetermined flow rate of the aerosol-forming substrate into the atomizing core 12. The processing unit 22 is implemented as a control circuit, such as an integrated circuit (IC).

[0053] In another embodiment, the processing unit 22 is configured to obtain viscosity information of the aerosol-generating substrate detected by the viscosity sensor 16. The received viscosity information is then incorporated into a temperature-operating voltage equation to determine the operating voltage of the micropump 131 corresponding to the current viscosity information. The processing unit 22 then controls the voltage output by the battery 21 to the micropump 131 to be the operating voltage corresponding to the current viscosity information, thereby causing the injection assembly 13 to inject a predetermined flow rate of the aerosol-generating substrate into the atomizing core 12.

[0054] The present embodiment provides an electronic atomization device, which includes an atomizer and a battery rod, wherein the battery rod is coupled to the atomizer; the atomizer includes an atomizer core and a spray assembly, wherein the spray assembly is used to spray a predetermined flow of an aerosol generating matrix to the atomizer core to generate droplets, and the atomizer core is used to atomize the droplets to generate an aerosol. The present application detects the temperature information of the aerosol generating matrix through a temperature sensor or detects the temperature information of the aerosol generating matrix through a viscosity sensor, and then controls the spray assembly to spray a predetermined flow of the aerosol generating matrix to the atomizer core according to the temperature information or viscosity information of the aerosol generating matrix, so that the aerosol generating matrix can maintain a predetermined flow rate for spraying under any temperature or viscosity conditions.

[0055] Please refer to FIG3 , which is a flow chart of an embodiment of a method for controlling an atomizer provided in the present application.

[0056] This embodiment provides a method for controlling an atomizer, comprising the following steps. The method for controlling an atomizer provided in this embodiment is applied to the electronic atomization device described in the above embodiment, and the atomizer control method is executed by the processing unit in the battery rod. The aerosol-generating substrate used in this embodiment is a liquid at room temperature.

[0057] S1: Pre-construct the viscosity-operating voltage relationship that needs to be satisfied for the spray assembly to spray a predetermined flow rate of aerosol-generating matrix.

[0058] Specifically, based on aerosol generating substrates with different viscosity data and the operating voltage of the injection assembly corresponding to each viscosity data when the injection assembly injects a fixed amount of aerosol generating substrate per unit time, a viscosity-operating voltage relationship corresponding to the aerosol generating substrate is generated.

[0059] In one embodiment, due to the varying viscosities of the aerosol-forming substrate, the operating voltage of the spray assembly varies when spraying a fixed amount of aerosol-forming substrate per unit time. The greater the viscosity of the aerosol-forming substrate, the less easily the spray assembly can spray the aerosol-forming substrate. In other words, the greater the viscosity of the aerosol-forming substrate, the smaller the amount of aerosol-forming substrate that can be sprayed per unit time by the spray assembly. If the spray assembly is to spray a fixed amount of aerosol-forming substrate per unit time, the power supply must be adjusted to provide a higher operating voltage to the spray assembly. In other words, if the operating voltage of the spray assembly remains constant, the amount of high-viscosity aerosol-forming substrate sprayed by the negative pressure generated by the spray assembly will decrease. Therefore, a higher negative pressure is required for the spray assembly to spray a predetermined flow rate of aerosol-forming substrate. If the operating voltage of the spray assembly remains constant, the amount of low-viscosity aerosol-forming substrate sprayed by the negative pressure generated by the spray assembly will increase. Therefore, a lower negative pressure is required for the spray assembly to spray a predetermined flow rate of aerosol-forming substrate.

[0060] To determine the relationship between viscosity and operating voltage, the spray assembly was regulated to spray a fixed amount of aerosol-generating substrate per unit time. Aerosol-generating substrates corresponding to different viscosity values ​​were sprayed through the spray assembly. The spray assembly was regulated to spray a fixed amount of aerosol-generating substrate per unit time, and the operating voltage of the spray assembly was recorded while spraying the fixed amount of aerosol-generating substrate corresponding to the different viscosity values ​​per unit time.

[0061] Through tools such as matlab / excel, based on the viscosity data and the working voltage corresponding to the injection assembly, the viscosity (μ)-working voltage (V) relationship corresponding to the aerosol generating matrix is ​​fitted, that is, V=f(μ). In this embodiment, there are ten viscosity data corresponding to the aerosol generating matrix. In other words, the viscosity data of the aerosol generating matrix can be 10cP, 15cP, 20cP, 25cP, 30cP, 35cP, 40cP, 45cP, 50cP, and 60cP, respectively. The mass of the aerosol generating matrix injected per unit area by the injection assembly is set to 3 mg. In other words, the predetermined flow rate of the aerosol generating matrix injected by the injection assembly to the atomizing core is 3 mg / s / cm 2 .

[0062] Different aerosol-generating substrates have different corresponding viscosity (μ)-operating voltage (V) relationships. When the aerosol-generating substrate is changed, for example, when the storage bottle for a different type of aerosol-generating substrate is replaced, the corresponding viscosity (μ)-operating voltage (V) relationship must be refitted based on the updated aerosol-generating substrate.

[0063] S2: Pre-construct a temperature-operating voltage relationship that needs to be satisfied for the spray assembly to spray a predetermined flow rate of aerosol-generating substrate.

[0064] It is understood that because the same aerosol-forming substrate has different viscosities, i.e., different fluid characteristics, at different temperatures, when the ambient temperature in which the user uses the atomizer changes, it is necessary to control the operating speed of the spray assembly based on the ambient temperature to achieve a predetermined flow rate of aerosol-forming substrate to the atomizer core at different ambient temperatures. For example, in winter, when the temperature difference between indoor and outdoor is large, the user's puffing while walking between indoors and outdoors will cause the ambient temperature of the atomizer to change significantly.

[0065] Specifically, the specific steps for obtaining the temperature-operating voltage relationship are as follows.

[0066] Please refer to FIG4 , which is a flow chart of a specific embodiment of step S2 in the atomizer control method provided in FIG3 .

[0067] S21: Based on the acquired temperature data of each aerosol generating substrate and the viscosity data corresponding to each temperature data, a temperature-viscosity relationship corresponding to the aerosol generating substrate is generated.

[0068] Specifically, for different types of aerosol-forming substrates, the substrates are heated to different temperatures, and viscosity data of the substrates are measured using a viscosity sensor, while temperature data of the substrates are measured using a temperature sensor. Using tools such as MATLAB / Excel, the viscosity data and the corresponding temperature data are used to fit the corresponding viscosity (μ)-temperature (t) equation for the aerosol-forming substrate, i.e., μ = f(t).

[0069] Different aerosol-forming substrates have different corresponding viscosity (μ)-temperature (t) relationships. When the aerosol-forming substrate is changed, for example, when the storage bottle containing a different type of aerosol-forming substrate is replaced, the corresponding viscosity (μ)-temperature (t) relationship must be refitted based on the updated aerosol-forming substrate.

[0070] S22: Determine a temperature-operating voltage relationship based on a temperature-viscosity relationship and a viscosity-operating voltage relationship of the aerosol generating substrate.

[0071] Specifically, the temperature (t)-operating voltage (V) relationship corresponding to the aerosol generating matrix can be calculated based on the viscosity (μ)-operating voltage (V) relationship and the viscosity (μ)-temperature (t) relationship corresponding to the same aerosol generating matrix.

[0072] In another embodiment, a temperature-operating voltage relationship is generated based on aerosol generating substrates of the same material corresponding to a plurality of different temperature data and an operating voltage of an ejection assembly corresponding to each temperature data when ejecting a predetermined flow rate of the aerosol generating substrate.

[0073] Specifically, the aerosol-generating substrates are of the same type, adjusted to different temperature conditions, and then ejected through the ejection assembly to eject a predetermined flow rate of the aerosol-generating substrate. The operating voltage of the ejection assembly corresponding to each temperature data is recorded. The temperature data of the aerosol-generating substrate include 15°C, 18°C, 21°C, 24°C, 27°C, 30°C, 33°C, 36°C, 39°C, 42°C, etc.

[0074] Based on the temperature data and the working voltage corresponding to the injection assembly, the temperature (t)-working voltage (V) relationship corresponding to the aerosol generation matrix was fitted using MATLAB / Excel, that is, V = f(t).

[0075] In this embodiment, the type of aerosol generating substrate is associated with the temperature (t)-operating voltage (V) relationship corresponding to the aerosol generating substrate and the viscosity (μ)-temperature (t) relationship corresponding to the aerosol generating substrate and stored in the storage unit.

[0076] S3: Obtain detection information of the aerosol generating matrix.
